Issues to consider Before proposing a specific load balancing solution, we need to start by explaining some of the things we need to consider when designing a load balancing system. The first thing to say is to pay attention to the high availability and scalability of the loa

1. OverviewThe first two times in this article, we have been talking about the construction of Nginx + keepalived. At the beginning of this article, we are going to honor the promise of the previous article, the following two articles we will introduce the Nginx + keepalived and LVS + keepalived to build a highly available load layer system. If you do not know about Nginx and LVS, see my previous two articles, "Architecture Design:
JBOSS via Apache Load Balancing method one: Using MOD_JKIn the first to second section of this article, we use Apache in the Linux environment and the front end of Windows to realize load balancing using IIS through AJP protocol and back-end jboss communication, and the corr
The size of the Internet doubles every one hundred days. The customer wants to achieve uninterrupted availability within 7 days and fast system response time, rather than repeatedly seeing a site "server too busy" and frequent system faults.
As the business volume increases, the traffic volume and data traffic increase rapidly, the processing capability and computing strength of each core part of the network also increase, making it impossible for a single device to undertake. In this case, if
After multiple tomcat servers are used for load balancing, the tomcat port is not open to the public, so the tomcat server Load balancer can be accessed precisely.
Background:
Use Nginx and two Tomcat servers to achieve load balancing, disable tomcat ports (8080 and 8090)
Use Docker to quickly create. Net Core2.0 Nginx Load Balancing nodes and dockernginx

device in front of the cluster to achieve traffic distribution.Load Balancing (Balance), which means that load (work tasks, access requests) are balanced and distributed across multiple operating units (servers, components) for execution. is the ultimate solution for high-performance, single-point-of-failure (high availability), scalability (horizontal scaling).This article is the first article on

Vaguely or many years ago, was responsible for a relatively large project (China Telecom BDC), load balancing is indispensable. Hardware asked a lot of vendors, software has also tried some influential tools. According to the company at that time, the background of the project and the actual situation, the choice is the hardware scheme, the purchase of equipment is F5.Time goes by quickly, hardware always m
Four common methods for server load balancing in enterprisesIn order to improve the performance and workload of the server, enterprises usually use the technology of DNS server, network address translation and so on to realize multi-server load balancing, especially the Internet web sites of enterprises outside, many o

I. The concept of clustering and load balancing
(i) the concept of clusters
A cluster (Cluster) is a loosely coupled collection of compute nodes consisting of two or more node machines (servers), providing a single customer view of network services or applications (including databases, Web services, and file services), while providing a fault recovery capability close to a fault-tolerant machine.
